Energetic Salts of a Tri-Annulated Ring System
Inorganic Chemistry, 2023Energetic salts of a triazolyl-tetrazinyl-aminotriazine ring system are characterized as energetic materials. Previously known sodium, ammonium, hydrazinium, barium, and triaminoguanidinium salts as well as the parent free acid were synthesized according to literature procedures and fully characterized for the first time as energetic materials.

Polycyano‐Anion‐Based Energetic Salts
Chemistry – A European Journal, 2008AbstractEnergetic salts based on polycyano anions and cations with a high nitrogen content tend to have extensive hydrogen bonding and exhibit heats of formation up to ΔHf=1579.1 kJ mol−1. Based on theoretical calculations, some of the new salts may be considered to be low‐energy monopropellants.

Energetic salts from nitroformate ion
Journal of Molecular Modeling, 2015Development of new energetic salts is the key factor in replacing low performance compounds in conventional formulations of high explosives as well as propellants. Ten salts based on the nitroformate anion and various nitrogen-rich cations were designed and their geometric optimizations carried out using the density functional method.

1,2,4‐Triazolium‐Cation‐Based Energetic Salts
Chemistry - A European Journal, 2008Abstract3,4,5‐Triamino‐1,2,4‐triazole (guanazine, 1) can be readily methylated with methyl iodide yielding methylguanazinium iodide (2). Salts containing the novel methylguanazinium cation with energetic anions were synthesised by metathesis reactions with silver azide (3), silver nitrate (4), silver perchlorate (5), sodium 5,5′‐azotetrazolate (6 ...

A π-stacking highly stable insensitive energetic inner salt and its insensitive energetic salts
CrystEngComm, 2023The energetic inner salts of π–π stacking and their energetic ionic salts show high thermal stability (Td ≥ 238 °C), insensitivity (FS ≥ 360 N, IS ≥ 40 J), and good detonation performance (D ≥ 7757 m s−1, P ≥ 24.1 GPa).

Computational Characterization of Energetic Salts
The Journal of Physical Chemistry C, 2007Using the experimental (or calculated) values for densities, a combination of theoretical and empirical calculations are powerful tools in predicting heats of formation of energetic salts. The heats of formation of cations and anions and lattice energies were calculated separately based on Born−Haber energy cycles.

Energetic Salts from N-Aminoazoles
Inorganic Chemistry, 2004New energetic salts (2, 3, 5, 6, 13, 14, 21, 22) were synthesized via the quaternization of derivatives of N-aminoazoles with nitric or perchloric acid or with iodomethane followed by metathesis reaction with silver nitrate or silver perchlorate.

Salts of Methylated 5-Aminotetrazoles with Energetic Anions
Inorganic Chemistry, 20071-methyl-5-aminotetrazole (4, MAT) can easily be protonated by strong acids, yielding known but largely uninvestigated 1-methyl-5-aminotetrazolium nitrate (4a) and perchlorate (4b). Methylation, rather than protonation, of 4 with iodomethane followed by the exchange of the iodide (5a) for nitrate (5b), perchlorate (5c), azide (5d), and dinitramide (5e)

Dalton Transactions, 2020
A series of energetic compounds based on nitropyrazole and dinitromethyl group were synthesized. The hydroxylammonium salt 7b exhibited satisfactory calculated detonation performance and the potassium salt 5 could be used as a potential green primary explosive.

Novel dinitromethyl-featured polynitro energetic salts
Dalton Transactions, 2016An unique and facile method was developed to synthesize a new class of energetic salts based on 2-amino-1,1,5,5-tetranitro-4-oxo-3-aza-pentene (ATNP) anion in one-pot reaction. These salts exhibited promising detonation performances (detonation pressure: 28.6 to 34.3 GPa; detonation velocity: 8037 to 8674 m s−1) which were comparable to those of RDX.
